Ultimately, choosing the right necklace length comes down to personal taste and how you plan to wear it.

This term specifically refers to a pearl necklace measuring 40 centimeters. More flexible than a collar necklace, it suits all necklines.
At 42 centimeters, this necklace sits just below the base of the neck. It's a favorite among women today, and looks stunning with classic tops or open necklines.
At 45 centimeters, the princess-length necklace is a timeless classic. It works with virtually every neckline and dress style, resting on the upper chest to beautifully highlight the décolleté.
This mid-length necklace, ranging from 50 to 60 centimeters (also called a "Matinée"), pairs beautifully with a tailored suit jacket.
Ranging from 70 to 90 centimeters, an opera-length necklace is incredibly versatile - equally at home with formal attire or a dressed-up look.
Over 90 centimeters, this style is iconic of the Roaring Twenties. Popularized by Coco Chanel in the 1930s, she famously wore it in pearl.
